Still a little anxious

So After unprotected sex on July 28th with a stranger who status was unknown I met a new guy my current boyfriend a few weeks later And started having Protected sex with him (vaginal and oral) except when he went down on me (he was a Virgin when I met him, no other sexual experience ( no tats or drug user) tested negative to hiv at 103 days, and at 175 days, i relaxed. In march (about 7 months after we started dating he tested negative to all std's. I started performing unprotected oral sex on him. (About a week later I guessing.. I got a cold (sore throat, headache, running nose, cough with phlegm. I still have my sore throat, and last night work up and my chest was all sweaty!)
I got tested again on Monday, 265 days after exposure ( again negative)

So my question is.. Is there any chance I could have given my boyfriend hiv?
If I was his only risk factor for catching it?
I suffer from severe stress and anxiety and going to see someone tomorrow about it.
